"You're looking at a species of flimsy little two-legged animal with extremely small heads whose name is Man. Warren Marcusson, age thirty-five. Samuel A. Conrad, age thirty-one... They're taking a highway into space, Man unshackling himself and sending his tiny, groping fingers up into the unknown. Their destination is Mars, and in just a moment we'll land there with them."
Marcusson, the optimist that believes people are alike all over, is killed when their ship crashes on Mars. Conrad is terrified when he hears someone banging on the outside of the ship. He is relieved when he sees that the martians are human looking, but telepathic. The next day, the Martians give Conrad a home of his own. Left alone, he quickly realizes there are no windows and all the doors are locked. Suddenly, a wall slides up, revealing bars through which a crowd of Martians stand. Conrad then realizes he is in a zoo. He cries out, "Marcusson, you were right - people are alike everywhere.""Species of animal brought back alive. Interesting similarity in physical characteristics to human beings in head, trunk, arms, legs, hands, feet. Very tiny undeveloped brain; comes from primitive planet named Earth. Calls himself Samuel Conrad. And he will remain here in this cage with the running water and the electricity and the central heat as long as he lives. Samuel Conrad has found the Twilight Zone."
Notes: Third consecutive intro beginning with the phrase "You're looking at". There's only one other streak of three consecutive episodes (episodes 75 through 77) in which the intros have even the first word in common ("The"). The three episodes were written by three different writers, which suggests that Serling probably at least contributed to the intros of the two episodes he didn't write. The "What You Need" and "Young Man's Fancy" intros also begin with "You're looking at...", while "The Mighty Casey" and "The Old Man In The Cave" intros begin with "What you're looking at...".
